To elem it THU/{j concern: the electrolytic action will be Very feeble,

Iii ii wn that I, JAMES S. STEWART. e citizen of the ll'niled States, residing at the. c ty New York, in the county of New 3 irk and State of New York, have invented certain new and useful In] rorements in Outdoor Receptacles, oi whic 1 the following r. lull, clear, and exact description.

My invention relates to 2], form of incan- ;cscem imp rccept a-cle particularly adapted for out-door wiring.

The principal objectof the invention is to provide it receptacle of this class, which is absolutely protected against the weather and storms, or ingress of water from any source i a object of the in critic-n is to or we u receptacle of this class. which has .use ci'iibodied therein.

Still further objects ore to provide for the oration of all parts which are at a 1 ol electric potential in use, and to obtain. a con'iolele practical mid lump socket, which economical turc, rind durable in use.

l other objects iew, my

location and in the arrangehercinzitter set forth and sho pzu'liculurly pointed out in the appended claims.

In tire drawings: Figure l is a side elevsk tion of u receptacle embodying the principles. of my invention; Fig. 2 is it vertical section-til View of the same; Fig. 3 is it. top View ith the fuse cup removed; Fig. l is on inside View oi. the fuse cup; Fig. 5 is a bottom; .w ol" the receptacle with the usual tliresdoti shell r moved.

1 ll ut-door wiring, the most serious t arises by reason of \Yit-lOJ and dampporl ions is dompc c urrentwhere the metallic q are exposed. "lh

d pxtth for the elect; til pdrts or terminals o dill'ereni and the electrolytic notions, set up, immediately disintegrate troy the metals sub et-led to it. ln ut my inyr-uli to protillic ports against nigress of r this is possiblev to be :iti I further iiirrnngc thru the parts. dificrcut potential in r= rmul use sepzirstcd in the socket, so that Jug into thrinterior ports of the hold the metallic parts;

even it" a little moisture should get into the socket by any possible contingency. In addition to the above purposes I also incorporate ilfuse in each receptacle so' arranged that it perfectly protected egeinst moisture, and further in such a way that it is imossiblc for the fuse to be wrongly connected into the socket by ignorant or careless workmen. In this way the circuit is adequately rotectcd by the fuses of the individual cm s, so thatthe danger and annoyance of line fuses blowing frequently, is wholly overcome, In carrying out my invention, I make use of a porcelain housing, which is formed and apertured with the necessary holes, and which is adopted to receive'and With this porcelain housing is associated a cap which closely engages the housing and which forms a. supplemental chamber or housing for the fuse.

Referring now to the drawings in which like parts are designated by the same reference sign, 1 indicut es the housing of porcelain or suitable material, which is open at its lower end 2, bu t which completely and integrally closed at the upper end 3, except for certain holes or perforations hereinafter described. The housing, therefore, forms an inverted cup all of integral porcelain and having a central protuberance or boss 4, which extends axially of the housing toward its open end 2. This boss or protuberance is axially apcrtured to receive a metallic tmn 6 which n slilllltS llltl (.Olltl'tll HEIDI" nal for the lamp.

The thrmtded shell is imucmed at T, and is ol the ordinury l'orm, except that in practice I slightly emboss the metal ill the points 8, so as to enter orrcspondlng recesses t), in the housing. The purpose of this is to give a lirm anchorage against the shell being turned when the lamp is screwed into place. The inner end ol' the. shell receives a porcelain button it), which also has :1 central hole to receive the stem (3.

ll. designates 1L metallic washer, which is held in place on the button ll), by u hezidcd port 12, ol the stem ti. The details of the washer ll and tho l'nstcning 1'! may be of any desired character in practice.

The shell 7 is designed to be held lirmly in place by cement. which also embeds ilsell around the various metallic connections; This cement is poured into place ultcr the shell has been positioned and the connecdrawing it tight. In this relation the buttions are made, as will. hereinafter appear, but before GOIISIdGI'HIg these connections I Will refer to the details of the fuse and its 13 indicates the fuse cap, and in practice I makethis part and the housing 1 with interlocking bayonet joints, which are integrally molded in the construction. The housing has ribs 14, and the cap has ribs 15, which are engaged together by properly positicn mg the cap and housing and turning them relatively to one another through a predetermined angle. such as to form within it a chamber 16, which I shall term the fuse chamber.

The upper surface of the end of the housing 1 is inset with metallic plates 17 and 18, and the wall or partition 19 conveniently of orcelain, and integral with the body of the housing is interposed between the two plates.

The form of the cap 13 is x As clearly indicated. in Fig. 3, this wall or partition 19 15 formed so as to almost wholly surround the central plate 17, which is conlamp. This connectionis eonvenientlymade by screwing the stem 6 into the plate 17.

20 indicates a second partition or wall which is curved concentrically with the axis of the housing in practice. The arrangement of the walls 19 and 20 is such to form a circuitous groove or channel between them, and in this channel the fuse is designed to be placed. I

21 and 22 indicate screws which constitute binding posts for the reception of the fuse wire 23. i

I will now refer to the necessary operations by which the parts of the receptacle are conveniently assembled. For this mrpose, a wire 24 is first soldered to the shell 7, and another piece of wire 25 is bared at one of its ends .26. The wire 25 is then inserted with its bared end foremost through the counterbored entrance of a hole 28, and the other end of the wire is passed through another hole 27in the housing. The purpose of hav ing the hole 28 of counterbored form is to bar the entrance of the wire beyond the point where the insulation or unbared portion brings it against the shoulder formed by the reduced portion of the hole. The construction is clearly indicated in Figs. 2 and 5, in which the shoulder against which the insulation brings up, is indicated at 29. The extremity of the wire projects upward into the chamber 16, and is soldered to the plate 18, which may be drilled with an opening for this purpose. in this way the wire 25 is firmly locked into place snugly wiihin the upper part of the receptacle and a direct connec-- tion established with the plate 18. The shell 7 to which the wire 2t is attached, is new drawn into place by the expedient of passing the wire 24 through a hole 30, and

nected to the central stud terminal of the 2 ton 10 is'central with respect to the boss or protuberance 4, so that the stem 6 may be p051 honed and screwed into the plate 17. it

is now merely necessary to pour 111 the cement which can be done through any con venient hole or opening 31 (Fig. 1). The cement flows around the shell 7 and aroundall of the exposed parts of the wires g4. and 25 and their connections. The cement also flows into the stud or protuberance a so as to embed the stem (5 properly into place and firmly hold the central stud terminal. Channels or recesses 32 are conveniently left in the end of the protuberance for this purpose. The fuse wire 23 now being connected up in an obvious manner between the screws 21 and 22, and the cap 13 being fastened into place, the receptacleis complete and ready for use.

A feature of the invention relates to the relation between the wall or partition 19 and the cover 1.3. {this partition has its top edge formed to closely conform to the inside surface of the cap, and the relation of these is so close fitting that if an ignorant or careless worlunan connects the fuse across the top of the partition, instead of through its proper channel, the fuse will be cut off by the engagen'ient of the cap. Thus the fuse cannot be operatively connected exceptthroug'h its proper circuitous channel, and this channel is so long and so round-about that danger from. an arc is altogether obviated, even if the receptacle is: used with high voltage lamps. in addition to this object, the partition serves to preclude. any improper connection with the fuse'terininal by wire nails or thick wires, or other improper connecting means. All of the exposed terminals within the fuse chamber are, of course, normally at about the same potential because of the neglible resistance of the fuse. Accordingly the presence of dampness in this chamber, while desirable to avoid, is not necessarily fatal to the proper working of the lamp. However, I shape the cap 13 pointed on its upper surface so as to shed water, and it will be observed that the edges of the cap overlap the adjacent surfaces of the housing, so that thewatcr is shed away from the housing, and

does not enter the fuse chamber.

The parts whose potential is widely different. that is to say, the wire 24 and the wire 25, and also the shell 7 and the stem 6, are not only very thoroughly shielded against ingress of water, but are widely separated and have interposed porcelain walls, so that electrolytic action is amost wholly precluded. it will be seen that the wires 24 and 25 enter the housing at diametrically opposite points where they are completely embedded in cement. The central protuberance or boss 4 is long enough to prevent the shell 7 being drawn into the socket an undue distance, and in ractice I make the protuberance 4 so long that the shell is held widely apart rom the wire 25, which is snugly located at the extreme inner part of the cavity. There is, therefore, a considerable'distance between the parts oi diflerent potential, and a thick insulating barrier of cement. The stem 6 is wholly surrounded by the porcelain boss, so that its insulation is al'isolute, and the button 1.0 serves to shield the central washer 11 from the wire 24. Thus the parts which it is important to insulate thoroughly and protect against moisture adequately, are so protected and electrolytic action is insured against.

The socket is connected to the circuit wires by soldering the connection wires 24. and 25 thereto. In'this relation the receptacle hangs down and the water is shed off its lower edge. The only p ace where there is any possibility of water entering is at the holes 27, 30 and 31, but these are at this time acked with the cement which has been injected so that the water cannot enter. Since the receptacle always hangs with its open end downward. its dry condition is bound to be maintained.

1. A lamp receptacle for out-door Wiring, comprising a housing in the form of a cup with a central boss or protuberance, a she l having a wire extension drawn into said housing and having a button bearing against said protuberance, and a central stud connection for the lamp extending through said protuberance.
